Just looked at the spec and the following are the paid for optional extras:
CSL wheels
leather
idrive/sat nav
xenons
front parking sensors
6 CD Changer
Built-In Rear Window Blinds
Electric Rear Screen Blind
Everything else mentioned in the advert is standard on every 330d (I know, I used to own an 06 330d
)
Gives you an idea of what extras you are getting for your money.....
Oh, and the average consumption is not 46mpg combined - its more like 38mpg (unless you drive like miss daisy).
